Product Detail

Product Description

Polypropylene resin can be classified into various categories. According to the different spatial positions of methyl groups (-CH3) in the polypropylene molecule, it can be divided into three categories: isotactic, syndiotactic and atactic. According to the polymerization process, the polymerization of isotactic polypropylene can be divided into slurry method, bulk method, solution method and gas phase method. According to the use of PP granules, it can be divided into flat yarn (narrow tape), fiber, film, extrusion, blow molding, injection molding, etc.

Product Applications :

(1) Woven products. The polypropylene PP consumed by woven products (plastic woven bags, tarpaulins and ropes, etc.) has always accounted for a high proportion in China, and it is also the largest market for polypropylene consumption in my country, mainly used for the packaging of food, fertilizer and cement.

(2) Injection molded products. Injection products are mainly used in small household appliances, daily necessities, toys, washing machines, automobiles and turnover boxes.

(3) Film products. PP film grade mainly includes BOPP, CPP, ordinary packaging film and microporous film, etc. BOPP has many excellent characteristics such as light weight, high mechanical strength, non-toxic, transparent, moisture-proof, etc., and can be widely used in packaging, electrical, electronic appliances, tapes , label film, film, composite and many other fields, of which the packaging industry is the most used.

(4) Fiber products. Polypropylene fiber refers to a fiber product made from polypropylene as raw material by melt spinning. Because polypropylene fiber has many excellent properties, it is widely used in the three fields of decoration, industry and clothing, and has become the second largest variety of synthetic fibers.

(5) Pipe. Polypropylene pipes have the characteristics of high temperature resistance, convenient pipe connection (thermal welding, electric welding, pipe connection), and recyclability. They are mainly used in building water supply systems, heating systems, farmland water delivery systems, and chemical pipeline systems.
